Phaulula apicalis sp. nov.

(Plate 2 a–g, plate 3 a–g)

Holotype: female, China: Hainan Island: Baisha, Yinggeling Nature Reserve, 2005. VIII.29-IX.4, Coll. Liu Chunxiang ( IZAS).

Paratype: 1 female same data as the holotype; 1 female, China: Hainan Island: Baoting, 80m, 1980. VII.24, Coll. Li Changqing ( IZAS); 1 male, China: Guangdong: Dianbai, Xiaoliang, 1982. VI.12-17, Coll. Xie Yingshu ( MSIE); 1 female, China: Guangdong: Taishan, Shangchuan Island, 1989. VII.4, Coll. Liang Geqiu ( MSIE).

Description. Female (holotype). Size median. Fastigium verticis dorsally sulcate, with apex obtuse, not deflexed, narrower than the first segment of antennae, not joining the fastigium frons. Antennae thin, long, flexible. Compound eyes produced. Pronotal disc with prozona smooth and metazona flat, with longitudinal median carina complete and without lateral carina; anterior margin approximately straight, posterior margin obtuse rounded; median transverse furrow “V”-like; lateral lobe of pronotum higher than long, with anterior margin slightly concave, ventral margin oblique backwards, and posterior margin slightly obtuse; humeral sinus distinct.

Tegmen extending beyond apex of posterior femur, hind wing longer than tegmen. Costa vein not distinct, Sc and R running close until the middle of tegmen. Rs vein branching from the middle of the tegmen, not bifurcate; R stem also with more 3 lateral branches to the posterior margin of tegmen. Anterior coxae with a distinct spine. Anterior femur with 5 interior ventral spines; median femur with 4 exterior ventral spines; posterior femur with 5 exterior and 7 interior ventral spines. Anterior tibiae dorsally sulcate; median femur with 3 interior dorsal spines; posterior tibiae with 32 exterior and 35 interior dorsal spines. Each genicular lobe with 1 large and 1 small spines.

Supra-anal plate triangular. Cerci conical, incurve. Ovipositor rather narrow, as long as two and a half times of length of pronotum, with lateral surface smooth, apex of dorsal margin sharp, apical sixth part of dorsal margin and apical 1/4 part of ventral margin crenulated (Plate 3f). Subgenital plate pentagonal, with lateral margin convex, and apical margin obtuse (Plate 3g).

Male. Structure of tegminal veins similar to the female (Plate 2a). Stridulatory file on underside of left tegmen cambered on the whole, basal eighth part with about 20 fine teeth, which gradually becoming larger distad, and remaining seven eighths part with about 50 densely arranged equal-sized big teeth (Plate 2f, 3a). Tenth abdominal tergum strongly produced, in dorsal view, base widest, gradually narrowed until distal fifth, which bearing approximately parallel lateral margins, and wide triangular apical margin (Plate 2e, 3b); in lateral view, apical half slightly deflexed, with apical margin truncated, middle third dorsally swollen and distinctly ventrally concave (Plate 2d, 3c). Cerci distinctly longer than subgenital plate (Plate 2d, 3d). Subgenital plate with basal part wide, short, distal 2/5 slightly contracted, trapeziform, gradually narrowed, apical margin with a rather large short triangular notch, shaped into posterior lateral false styli; ventral surface with distinct central and lateral carinae (Plate 2g, 3e).

Color. Yellow green (green in life). Compound eyes brown. Antenna yellowish green. Tegmen green.

Measurements (mm). length of body: male 23.2, female 24.0; length of pronotum: male 5.5, female 5.5; length of tegmen: male 32.6, female 34.0; largest width of tegmen: male 8.4, female 8.0; length of hind wing: male 34.1, female 35.5; length of posterior femur: male 20.3, female 19.0; length of ovipositor: 13.0. Etymology. The name refers that the new species possesses special male and female apex. Discussion. The new species differs from other congeners by the shape of the male tenth abdominal tergum, the male subgenital plate, and the female subgenital plate.

Distribution. China (Guangdong Province, Hainan Island).
